Usage/Examples

    import * as MeetingHandler from "com.vanimeeting.demo";
    import * as EventEmitter from "events";

    class WebrtcCallHandler {
    constructor() {
    this.roomid = null;
    this.meetingRequest = null;
    this.evenetEmitter = new EventEmitter();
    }

    static instance = new WebrtcCallHandler();
    static getInstance() {
        if (WebrtcCallHandler.instance === null) {
            WebrtcCallHandler.instance = new WebrtcCallHandler();
         } else {
        return WebrtcCallHandler.instance;
        }
    }
    setup(roomid, userid, appName, userData) {
        if (this.meetingRequest === null) {
            const locaUserid =
            new Date().getTime() + "_" + Math.floor(Math.random() * 20);
            this.meetingRequest = MeetingHandler.meetingStartRequestObject(
                roomid,
                userid || locaUserid,
                "demo" || appName
            );
            this.meetingRequest.numberOfUsers = 2;
            this.meetingRequest.userData = userData;
            }
            return this.meetingRequest;
        }
    }

    export default WebrtcCallHandler;

First we have to import SDK.

    import * as MeetingHandler from "com.vanimeeting.demo";
    import * as EventEmitter from "events";

Then we have to call meetingStartRequestObject which returns meetingStartRequestObject modal and accepts roomId, userId, appId, and userData as its params where:

• roomId : is always unique string to join a meeting.
• userId : is always unique string respective to user.
• appId : can be any manual id given by user.
• userData : any extra data.

    setup(roomid, userid, appName, userData) {
        if (this.meetingRequest === null) {
            const locaUserid =
            new Date().getTime() + "_" + Math.floor(Math.random() * 20);
            this.meetingRequest = MeetingHandler.meetingStartRequestObject(
                roomid,
                userid || locaUserid,
                "demo" || appName
            );
            this.meetingRequest.numberOfUsers = 2;
            this.meetingRequest.userData = userData;
            }
            return this.meetingRequest;
        }
    }

Then we will initialize the meeting and establish the connection by calling init method.

    MeetingHandler.init();

Then we will call startLocalStream method of MeetingHandler which will ask for camera and mic permission, once given returns the localStream of the user itself. It accepts isVideoRequired and isAudioRequired as its params.

• isVideoRequired : boolean
• isAudioRequired : boolean

    MeetingHandler.startLocalStream();

Then we will call checkSocket method of MeetingHandler to establish a connection with web socket.

    MeetingHandler.checkSocket();

After the connection is established with the websocket we will recieve an onConnected event and pass event name "onConnected" as first params and pass callback function onConnected as second parameter which will call startMeeting method of MeetingHandler to start the meeting.

    MeetingHandler.eventEmitter.on("onConnected", this.onConnected);
    onConnected = () => {
    MeetingHandler.startMeeting();
    };

After the initiation of meeting we will recieve an onTrack event and pass that event as event name "onTrack" as first params and pass callback function onTrack as second parameter which will recieve track as a parameter which will be passed as a MediaStream to video tag.

    MeetingHandler.eventEmitter.on("onTrack", this.onTrack);
    MeetingHandler.eventEmitter.on("refreshTrack", this.onTrack);*
    onTrack(track) {
        if (
            track.track !== null &&
            track &&
            track.kind === "video" &&
            track.isLocalTrack
        ) {
            this.localVideoRef.current.srcObject = new MediaStream([track.track]);
            this.localVideoRef.current.play();
        } else if (track && track.track !== null && !track.isLocalTrack) {
        if (track.kind === "video" && track) {
            this.remoteVideoRef.current.srcObject = new MediaStream([track.track]);
            this.remoteVideoRef.current.play();
        } else {
        if (track && track.track !== null) {
          this.remoteAudioRef.current.srcObject = new MediaStream([
            track.track,
          ]);
            this.remoteAudioRef.current.play();
            }
        }
        }
    }
